Billlie release debut full album the collective soul and unconscious: chapter two featuring “ZAP” and “WORK,” showcasing bold concepts and self-identity themes.
Billlie has officially released their first full-length album, the collective soul and unconscious: chapter two. The group first introduced the project in January with the pre-release single “cloud palace ~ false awakening.” The group is known for their strong concepts and storytelling. Thus, the members use this album to express confidence, individuality, and emotional honesty.

The album features twelve tracks, including five remixes. It opens with “$ECRET no more,” a continuation of “everybody’s got a $ECRET” from the group’s second mini album. The song brings together an impressive team of collaborators. Los Angeles-based producer Jake K worked on the track alongside Swedish songwriter Andreas Öberg and lyricist Maria Marcus. In addition, member Moon Sua contributed to the lyrics, adding a more personal and emotional layer to the song. She said:
We’re finally releasing our first full-length album, and we’re confident to call it the most well-made album we’ve released so far because we have put a lot of effort into working on this album for a long time. Please send lots of interest for all 12 tracks in this album, including the title track, “ZAP,”’ and the sub-title track, “WORK.”
The album’s title track, “ZAP,” reflects the project’s central message. Through energetic production and direct lyrics, the song encourages listeners to block out outside noise and face their true selves. Moreover, the track emphasizes living in the present and embracing one’s identity without fear of judgment.
Alongside “ZAP,” the group will also promote the sub-title track “WORK.” Once again, Moon Sua participated in writing the lyrics. This time, she drew from personal experiences to encourage listeners to view their flaws as unique strengths rather than weaknesses.

Another standout on the album is “TBD,” which explores the uncertainty of an undefined relationship. Instead of leaving emotions unresolved, the song focuses on making deliberate choices despite confusion. Furthermore, members Siyoon and Haram helped write the lyrics, capturing the emotional tension and vulnerability behind the track.
Speaking about the release, Siyoon shared her excitement over the group’s first studio album. She also thanked fans for their continued support. She also expressed hope that listeners would connect with the album’s wide range of songs. Meanwhile, Haram explained that the group paid close attention to every detail of the album to avoid any regrets. She also encouraged fans to listen to the full project, including “TBD,” which she helped write.
Following the release of the collective soul and unconscious: chapter two, Billlie will continue promotions with both “ZAP” and “WORK.”
